Fat Cancels Effects Of Vitamin CFats in our stomach may reduce the protective effects of antioxidants such as vitamin C. Scientists at the University of Glasgow found that in the presence of lipid the ability of antioxidants, such as ascorbic acid (the active component of vitamin C), to protect against the generation of potential cancer-forming compounds in the stomach is less than when no lipids are present. Our results illustrate how diet can influence gastric biochemistry,........Go to the What-media-blog (Added on 4/1/2007 9:04:58 PM)
MRI Detects Most Missed Opposite Breast CancersUp to 10 percent of women newly diagnosed with cancer in one breast develop cancer in the opposite breast. Results of a major clinical trial show that magnetic resonance imaging (MRI) scans are highly effective tools for quickly identifying these opposite breast cancers, detecting diseased tissue that other screening methods missed.
In the new trial, conducted by the American College of Radiology Imaging Network (ACRIN) and funded by the........Go to the The-cancer-blog (Added on 3/28/2007 10:22:27 PM)

Cancer Gene Work By Destroying MessengerA new study suggests how a notorious cancer gene may contribute to tumor growth.
The insight emerged from a long-running study of a protein called PMR1, the key player in an unusual mechanism that cells use to quickly stop production of certain important proteins.
Scientists discovered that PMR1 is activated - or "turned on - by another molecule, an energy-packing protein called Src (pronounced "sark").
Discovered in 1977, Src became........Go to the The-cancer-blog (Added on 3/19/2007 10:03:35 PM)
Inflammation And Metastasis Of Prostate CancerMany would assume that "mounting an immune response" or "having your body fight the cancer" is a good thing.

Genes That Can Slow Cell DivisionCancer cells differ from normal cells in, among other things, the way they divide. When a normal cell complies with a signal telling it to divide, it also begins to activate a "braking system" that eventually stops cell division and returns the cell to a resting state. When that braking system is faulty, uncontrolled cell division and the growth of cancer can result. Weizmann Institute researchers studied this system of brakes, and identified........Go to the The-cancer-blog (Added on 2/26/2007 7:00:14 PM)
